1 Claim.

The present invention relates to a unitary brush assembly for machines used to brush the surface of electroplated strip material.

An object of the present invention is to provide a unitary brush assembly capable of removal from or placement in any brushing machine without damage to the brushing element mounted thereon.

Another object of the present invention is to provide a supporting member on which is mounted the brush and driving-means therefor.

A further object of the present invention is to provide a unitary brush assembly including a supporting member and means for guiding the supporting member into and out of the brush machine whereby damage to the brushing element on the supporting member is prevented.

Other objects and advantages will become apparent as the description proceeds, and reference is had to the accompanying drawings, in

which:

Figure 1 is a sectional elevation of the preferred construction of the present invention;

Figure-2 is a section on line IIII of Figure 1;

Figure 3 is an end view of Figure 1;

Figure 4 is a sectional elevation of the present invention, but showing a honing or grinding mechanism in combination with the brush assembly supporting member;

Figure 5 is a section on line V-'V of Figure 4,

and

Figure 6 is an end view of Figure 4. A

In the drawings, the numerals 2 and 3 represent the side frames of a brushing machine, each of which is provided with suitable openings for receiving a brush assembly unit.

The rotary brush assembly unit comprises a channel-like supporting member 45 upon which is mounted bearing housings 5, containing bearings of conventional design, for supporting the shaft 6 of the rotary brush 1. The supporting member 4 extends outwardly through the opening in the member 3 a sufiicient distance so as to support a motor 8, whose armature shaft 9 is directly connected to the shaft 6 in any conventional manner so as to constitute the direct driving means for the rotary brush. The rotary brush is wound upon a tube l0, which tubeis positioned on and secured to the shaft 6, in any conventional manner.

Secured to the shaft 6 on either side of the rotary brush are splash plates 12 which prevent water from reaching the bearings on said hou'sings 5. The bearing housings 5 should be of such width that they readily position themselves assembly.

within the openings in the spaced members 2 and 3.

The supporting member t is of a width greater than the diameter of the rotary brush I so that upon insertion or removal of the brush assembly unit, said supporting member protects the rotary brush from being damaged against the openings in said supporting frame. This supporting member 5, being of channel-like construction, fits snugly in the openings in the supporting frame and is slidably mounted on guide members it, which extend between and are secured, in any conventional manner, to the spaced members 2 and 3. Such a construction provides means whereby the brush assembly unit can be properly guided during its insertion into and removal from the brushing machine so that damage to the rotary brush is prevented. On the member 2 there may be provided, if desired,,stop plates l5 which position the brush assembly unit with respect to said member 2 when being inserted into the machine. The stop plates i5 are secured to the frame 2 by bolts l6.

As shown in Figures 4 to 6, inclusive, the supporting member a may be provided with a grinding or honing mechanism. This mechanism comprises a flat abrading member I? extending across the entire face of the rotary brush. This abrading member I! is supported in a receptacle I8, to which are secured lever arms is pivotally connected to supporting arms 20 carried by said member t. Extending through the supporting member a and pivotally connected to the receptacle id, in any conventional manner, is an ad- J'usting screw 2! extending into an internally threaded collar 22, which collar is contained in a housing 23 attached to the said member 6 and rotated in any conventional manner sothat'vertical movement may be imparted to said adjusting screw 2! to advance thehoning or grinding member H for contact with said rotary brush assembly, whereby the surface of said brush is maintained truly cylindrical. Mounting of the honing mechanism on said member 5 permits the brushing element to be trued before being placed in the machine proper. While this procedure may be advantageous insome cases, the honing mechanism maybe located, if desired, in the brushing machine apart from the unitary brush The present brush assembly unit is one of 'a number of such units which may be used in a brushing machine for conditioning the surface of strip-like-materia1s, and due to the fact that each brushing element and its driving means, is

directly connected and entirely mounted and can thereto, since various modifications may be made 10 without departing from the scope of the invention, as defined by the following claim.

We claim:

A brushing apparatus comprising a frame, a

unitary brushing assembly slidable endwise in 15 said frame, said assembly comprising an elongated inverted U-shaped supporting member, means carried by said frame ior supporting and guiding said supporting member, a. driving unit 5 secured to said supporting member adjacent one of its ends and adapted for disposition exteriorly of said frame. a rotary shaft extending longitudinally of said supporting member and secured thereto, and a rotary elongated brush carried by said rotary shaft.
